Product Description
The Amphenol Industrial MS3102A-28-21S is a high-performance circular connector built to MIL spec standards, featuring 37 female contacts for demanding electrical interconnections. Its design addresses critical requirements of military, industrial, and commercial applications where reliable and robust multi-way connectivity is essential. The box mount configuration allows for secure integration in equipment panels, enclosures, or test fixtures where a straight, fixed receptacle is desired.
Manufactured from high-grade aluminium alloy, the connector shell is plated with zinc cobalt for enhanced resistance to corrosion and mechanical wear. An olive drab chromate finish is typical, providing both environmental protection and minimized reflectivity. The IP67 rating ensures the assembly is dust tight and can withstand immersion in water, making it suitable for both indoor and outdoor environments where reliability is paramount.
The MS3102A-28-21S utilizes a screw coupling mechanism to achieve a secure, vibration-resistant connection and prevent accidental disconnection, critical in military, transport, and heavy industrial equipment. Its threaded coupling design and key/keyway polarization avoid mismating and ensure quick, accurate engagement during installation or maintenance.
The connector supports solder bucket contacts made from copper alloy and finished with silver plating, providing excellent conductivity and long-term durability under high load conditions. With a maximum supported voltage of 500 V to 700 V AC and a shell size of 28, the device integrates smoothly into a range of power, signal, and control systems. Its operating temperature range from -55°C to 125°C accommodates applications that face elevated thermal cycling or extreme ambient temperatures.
This Amphenol connector complies with the rigorous requirements of MIL-DTL-5015 and MIL-C-5015 standards, making it fully compatible with standardized military and commercial systems. Typical use cases include communication equipment, computers, shipboard systems, ground support installations, and other environments where mechanical integrity, environmental sealing, and stable electrical performance are required.
Strain relief features are incorporated to minimize cable bending and fatigue, enhancing the lifespan of the installed assembly. The insert is made of resilient synthetic rubber, ensuring high dielectric strength and additional vibration resistance. Standardized box-mount design means this connector is ideal for fitting into electrical cases, cabinets, and machine chassis.
In summary, the Amphenol Industrial MS3102A-28-21S delivers field-proven reliability, secure electrical contact, and rugged construction for critical applications across military, industrial, transport, and communications sectors.
